This is the true story of the plot to kill Stalin's Greatest Enemy, and it involves an ice axe, a bloody study in Mexico City, and a betrayal years in the making.

At its centre is Ramón Mercader, a Soviet-trained agent who infiltrated Leon Trotsky’s inner circle and killed him. But this was more than a simple murder - it was the result of Stalin’s ruthless drive to eliminate all rivals and consolidate power.

With us is Josh Ireland, author of "The Death of Trotsky: The True Story of the Plot to Kill Stalin's Greatest Enemy". He explains the shadowy politics of Stalin's Kremlin, and how manipulation and conviction put Mercader on a path to Mexico City...

Produced by James Hickmann and McKenna Fernandez, and edited by Matthew Wilson.

Trap doors under toilets, hidden radio rooms in the back of wardrobes, secret bases behind waterfalls....Dan investigates an extraordinary network of secret resistance cells set up during Britain's "darkest hour".

In the summer of 1940, Britain and its empire stood alone as the Nazi war machine stormed through Europe. Prime Minister Winston Churchill created something extraordinary: secret factions of men and women trained to wreak havoc behind the lines of an invading army.

Dan once again joins forces with Andy Chatterton from the Coleshill Auxiliary Research Team, who are unearthing this incredible part of World War Two for another bunker hunt. What they find on this adventure is truly extraordinary.

You can learn more about Britain's secret resistance in Andy's book 'Fortress Britain 1940: Britain's Unsung and Secret Defences on Land, Sea and in the Air'.
